Series MP Mini-Photohelic® Differential Pressure Switch/Gage

Compact, Low Cost Switch/Gage

The Series MP Mini-Photohelic® Differential Pressure Switch/Gage combines the time proven Minihelic® II differential pressure gage with two SPDT switching set points. The Mini-Photohelic® switch/gage is designed to measure and control positive, negative, or differential pressures consisting of non-combustible and non-corrosive gases. Gage reading is independent of switch operation. Switching status is visible by LED indicators located on the front and rear of the gage. Set points are adjusted with push buttons on the back of the unit.

NIST CALIBRATION available in Product Configurator.

Product Applications

Fume hoods
Dust collection
Pneumatic conveying
Clean room

Gage reading unaffected by switch operation and will continue to read pressure even during power loss
Visible switch status LED provides indication of set point switching state
Compact design but with the power of larger devices can meet the same application specifications
